Methodology

We took a close look at over 70 financial institutions, including the largest U.S. banks based on assets, debit card volume, Internet search traffic and other factors; the nation’s largest credit unions, based on deposits as well as broad-based membership requirements; and other notable and/or emerging players in the online banking industry. We rated them on criteria including digital experience and ease of mobile apps, as well as annual percentage yields, minimum balances, fees and more. For this roundup, we considered only those services with the highest scores for web and mobile experience within their respective categories that are widely available across the country.
